As Discourse is used also by people that care about free licenses - and as far as I understood Discourse is free GPL2.0
software and only uses free Ruby/JS code it would be nice to not see everything blocked.

LibreJS did not allow the execution of any scripts on this page: '
The inline and on-page JavaScript code may not be free and/or may not have proper license information and external scripts (if present) may have been removed by default.
External scripts may not be free and/or may not have proper licensing and are not part of the whitelist of free JavaScript libraries.

Is it possible that the JS shipped with Discourse gets the necessary license headers? This would be the first big part in allowing users of LibreJS to better view pages that use Discourse and take part in the discussions.

A forum on which this is important is the Fairphone forum (https://forum.fairphone.com/) as it has a significant share of users who use Android without Google services, probably about 10% of the mobile users, and many of them use the Icecat browser. While the forum used to work with Icecat 47, this is no longer the case with the recent Icecat 53 update.
